Nonlinear Analysis of Laterally Loaded Pile Group in Layered Soil–Ash Deposit

The current scenario for the geotechnical engineering is not only to take care of vertical load of superstructure impending to the soil but also the lateral load subjected to the structure must be taken into consideration for the safe design of foundation. For designing pile foundation, knowledge of load–deflection behavior of pile under moderate to heavy load is necessary. In the present study, numerical analysis of pile group in a layered soil–ash system has been performed using SoilWorks software. The analysis is based on P-Y curve method which is a realistic and practical method for the load deflection analysis of pile under lateral loads. The pile arranged in grid form in 3 × 3 and 4 × 4 pattern. The influence of pile diameter effects along with various pile spacing on the behavior of the pile–soil system has also been studied. The stability of pile was checked under horizontal and vertical condition. The pile group has been analyzed with vertical load, lateral load, and moment at the top end of the pile. The response of the pile includes horizontal displacement, shear force, moment, and ground reaction along the pile length.
